Here, we provide an integrative taxonomic revision of Rondonia, combining light and scanning electron microscopy with molecular analyses of SSU and LSU rDNA sequences. A new species, Rondonia pardensis n. sp., is described from the intestine of Metynnis lippincottianus (Cope) (Characiformes: Serrasalmidae) in the Pardo River, Paranapanema River basin, Brazil. The new species is distinguished by the presence of a pre-bulbar excretory pore with a protruding teardrop-shaped structure covering it, the number and organization of the cloacal papillae (two pairs pre-cloacal, two pairs ad-cloacal and six pairs post-cloacal), the mouth with three bilobed lips bearing double papillae on each side arranged radially and two amphids, and a larger body size in comparison to its congeners. Phylogenetic analyses confirm its placement within Atractidae and support the monophyly of Rondonia. Based on morphological and molecular evidence, we propose a new taxonomic combination for specimens analysed by Cavalcante et al. (2016), herein reassigned as Rondonia xapuriensis nom. nov. We also examined the type material of Rondonia rondoni deposited by Travassos (1920) using SEM, confirming diagnostic features and recording additional characters that contribute to an updated morphological characterization of the species. In light of these findings, we propose an amended generic diagnosis for Rondonia that reflects its phylogenetic coherence and morphological consistency, and also a key for the identification of the Rondonia species. This study expands the known diversity of the genus, clarifies historical taxonomic uncertainties, and emphasizes the importance of integrative approaches for resolving the systematics of Atractidae.</p>","PeriodicalId":54436,"journal":{"name":"Systematic Parasitology","volume":"102 6","pages":"58"},"PeriodicalIF":1.2,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145234211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This new species represents the second record of the genus Cardimyxobolus in Japan and the fourth species of the genus globally. The plasmodium of the new species is spherical, and its spores are ovate, appearing wider than long in valvular view.

The foramina of each polar capsule are positioned laterally at approximately one-third of the distance from the anterior end of the spore. Cardimyxobolus iriomotensis n. sp. can be distinguished from its congeners by the following key features: 1) a smooth shell valve, in contrast to the 1-6 V-shaped folds found in C. leshanensis; 2) significantly thinner spores (4.4-6.1 μm) compared to C. rhodeus (9.0-10.0 μm); 3) pyriform polar capsules, differing from the spherical capsules in C. leshanensis and C. rhodeus; and 4) narrower spore width (7.5-10.0 μm) and smaller polar capsules (2.6-4.0 μm × 1.4-2.7 μm) than those of C. japonensis (11.3-12.5 μm and 4.2-5.0 μm × 2.9-3.8 μm, respectively).

The new species is morphologically similar to C. exigua, the previously known species reported from the Eastern Pacific, in general shape of body, cephalon, the anterior pereonites, pereopods and pleotelson; however, they can be easily differentiated because adult females of the new species are larger and slender than those of C. exigua and because they show differences in the dorsal surface of pereonites, the shape of the seventh pereonite and cephalon and the relative size of exopodite and endopodite of the uropods. The new species is morphologically similar to C. exigua, the only species of Cymothoa described so far from the Eastern Pacific, particularly in the general shape of the body, cephalon, anterior pereonites, pereopods, and pleotelson. Nonetheless, it can be readily distinguished from C. exigua by several diagnostic features: adult females attain larger body sizes and exhibit a slenderer morphology especially in the ovigerous females; additionally, differences are present in the dorsal sculpturing of the pereonites, the shape of the sixth and seventh pereonites, and the relative proportions of the exopodite and endopodite of the uropods.
